could not convert string to float with sns.kdeplot

Question

I am trying to use sns.kdeplotto get a figure but I get the below error:

ValueError: could not convert string to float: '   0.43082    0.45386'

Do you know how I can fix this error?

Code snippet:

data=pd.read_csv('input.txt', sep="t", header = None)
sns.kdeplot(data=data, common_norm=False, palette=('b'))

input.txt:

It seems that the delimiter of your (.txt) file is not a tab but whitespaces actually. Try this :

data = pd.read_csv("input.txt", sep="ss+", engine="python", header=None)

Plot :

plt.figure(figsize=(6, 3))

sns.kdeplot(data=data, common_norm=False, palette=sns.color_palette("rocket", 2));
